To estimate an accurate position and an attitude state of an unmanned aircraft, and to allow the unmanned aircraft and a ground device to communicate with each other through a simplified constitution.SOLUTION: An unmanned aircraft control communication system includes an unmanned aircraft and a ground-side device. The ground-side device comprises: a light signal group irradiation part which emits a light signal group consisting of a plurality of light signals each including identification information substantially radially into a space such that mutual optical axis intervals gradually widen; and a ground-side light receiving element. The unmanned aircraft comprises: at least one aircraft-side light receiving element; a retroreflector; an optical shutter which is positioned in an optical path of retroreflection light by the retroreflector, and can control passing or cutoff of the retroreflection light; and an aircraft-side control part which uses identification information of a light signal to estimate a position and an attitude state of the unmanned aircraft, and also controls an optical shutter to generate a light signal for communication.SELECTED DRAWING: Figure 1

    【課題】無人航空機の正確な位置及び姿勢状態の推定と、簡略化した構成で無人航空機と地上装置との間の通信とを行うこと。【解決手段】無人航空機と地上側装置とを含む無人航空機制御通信システムであって、地上側装置は、識別情報をそれぞれ含んだ複数の光信号からなる光信号群を、相互の光軸間隔が徐々に広がるように概略放射状に空間に照射する光信号群照射部と、地上側受光素子とを備え、無人航空機は、少なくとも1の航空機側受光素子と、レトロリフレクタと、レトロリフレクタによる再帰反射光の光路に位置し、再帰反射光の通過と遮断を制御可能な光シャッタと、光信号の識別情報を用いた無人航空機の位置及び姿勢状態の推定と光シャッタを制御することによる通信用光信号を生成とを実行する航空機側制御部を備える。【選択図】図1
